Marchwood Power Station
Marchwood Power Station is an 898.1 MW gas-fired power station in Marchwood, near Southampton, England. It is situated beside estuary of the River Test where it meets Southampton Water, opposite the Port of Southampton. It is built on the site of an oil-fired power station, demolished in the 1990s. The station is operated by the Marchwood Power Limited Independent Team. Overview Marchwood Power Station is next to Southampton Water on Marchwood Industrial Estate. It is a combined cycle gas turbine (CCGT) power station. The plant uses compressed air and gas to power one turbine and then uses exhaust gases from that process to boil water and power a steam turbine. The power station generates 898.1MW of electricity. Water from the River Test is used as part of the cooling process. Around 45 people work at the power plant. History Oil-fired plant The first power plant at Marchwood was built in the 1950s. It was originally designed to be a coal-fired plant.''Civil Engineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hampshire
Hampshire (, ; abbreviated to Hants) is a ceremonial and non-metropolitan county in western South East England on the coast of the English Channel. Home to two major English cities on its south coast, Southampton and Portsmouth, Hampshire is the 9th-most populous county in England. The county town of Hampshire is Winchester, located in the north of the county. The county is bordered by Dorset to the south-west, Wiltshire to the north-west, Berkshire to the north, Surrey to the north-east, and West Sussex to the south east. The county is geographically diverse, with upland rising to and mostly south-flowing rivers. There are areas of downland and marsh, and two national parks: the New Forest and part of the South Downs, which together cover 45 per cent of Hampshire. Settled about 14,000 years ago, Hampshire's recorded history dates to Roman Britain, when its chief town was Venta Belgarum (now Winchester). The county was recorded in Domesday Book as divided into 44 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marchwood Incinerator
Marchwood ERF (or Marchwood Energy Recovery Facility) is a waste incineration plant in Marchwood, near Southampton, England. It is situated beside the estuary of the River Test where it meets Southampton Water, opposite the Port of Southampton. It burns municipal waste and produces electricity for the National Grid. History The first incinerator at Marchwood was a small plant which took refuse from Southampton and the New Forest, and was commissioned in 1975. This plant was closed in 1996. Demolition of the plant, which took place in 2010, was temporarily suspended when a pair of kestrels nested at the site. The new plant, commissioned in 2007, was built close to the site of the old incinerator. The plant is surrounded by a metal dome superstructure which was designed by the architect Jean-Robert Mazaud. The dome was built by the Texas company Geometrica. It was built using galvanized steel tubing joined with high-strength aluminium hubs, which was then clad in aluminium. See ...

Marchwood Power Station, East Road - Geograph
Marchwood is a village and civil parish located in Hampshire, England, United Kingdom. It lies between Totton and Hythe on the western shore of Southampton Water and directly east of the New Forest. The population of the village in the 2011 census was 6,141. History Marchwood has seen human activity since Roman times. The Roman road from the Calshot/ Lepe area passed through here on its way to Nursling (''Onna'' as it was called). Roman coins have been found at Bury Farm. The name "Marchwood" is most probably from the Old English "''merecewudu''" meaning "smallage wood" ("smallage" is a term for wild celery). It is mentioned in the Domesday Book of 1086 as "Merceode", when the manor was held by Alwin, whose father Wulfgeat held the manor before 1066. The manor of Marchwood eventually became known as Marchwood Romsey. John de Romsey held the vill of Marchwood in 1316. He was succeeded by Sir Walter Romsey of Rockbourne, who died in 1403–4 holding land in Marchwood. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in ...

Geothermal Heating
Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption. Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter. Geothermal energy originates from the heat retained within the Earth since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with tempera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Central Electricity Generating Board
The Central Electricity Generating Board (CEGB) was responsible for electricity generation, transmission and bulk sales in England and Wales from 1958 until privatisation of the electricity industry in the 1990s. It was established on 1 January 1958 to assume the functions of the Central Electricity Authority (1955–7), which had in turn replaced the British Electricity Authority (1948–55). The Electricity Council was also established in January 1958, as the coordinating and policy-making body for the British electricity supply industry. Responsibilities The CEGB was responsible for electricity generation, transmission and bulk sales in England and Wales, whilst in Scotland electricity generation was carried out by the South of Scotland Electricity Board and the North of Scotland Hydro-Electric Board. The CEGB's duty was to develop and maintain an efficient, coordinated and economical system of supply of electricity in bulk for England and Wales, and for that purpose t ...
